I always love speculating and I don't think anyone doubts we'll see more planets in the future. In fact, since someone uncovered the content we'll be seeing in the patches up to 1.5, it's pretty much a done deal (queue Bounty Hunter voice ).

So, like IGN's suggestions? Obviously, Kashyyyk and Dantooine are KotOR planets and would be very interesting to see. And I'm still hoping Telos will get some love.
